Characterized by using a liquid crystalline polymer for the formation of coverlay over flexible regions, the all-layer processing method has the advantage of preventing interlayer delamination, thereby providing a highly reliable rigid-flexible PCB which thus meets the recent requirements of electric appliances for low energy consumption, high frequency adoption, and slimness.

Abstract: The present invention relates to an apparatus for stacking semiconductor chips, a method for manufacturing a semiconductor package using the same and a semiconductor package manufactured thereby. The apparatus for stacking semiconductor chips may comprise two tables for supporting wafers, a picker for picking up semiconductor chips and a picker transfer unit for moving the picker vertically and horizontally. The method for manufacturing a semiconductor package using the same may allow easy and rapid stacking of semiconductor chips, thereby improving the productivity of semiconductor package manufacture. Further, a semiconductor chip having a relatively thick film is attached onto another semiconductor chip having a relatively thin film. The thicker semiconductor chip may protect the thinner semiconductor chip from faults such as chipping or warpage which may occur due to external shocks such as that caused by a picker, thereby improving the reliability of the package.

Abstract: A method is directed towards fabricating a printed circuit board (PCB) having a thin core layer. In the method, a substrate, where a copper foil is formed on a release film and a prepreg, is employed as a base substrate and a core insulating layer is removed after the fabrication of the PCB, thereby reducing the thickness of the final product.

Abstract: A rigid flexible printed circuit board (PCB) and a method of fabricating the same. Since a polyimide copper clad laminate is not used during the fabrication of the rigid flexible PCB, an increase in cost resulting from use of the polyimide copper clad laminate and poor reliability of adhesion at an interface between different materials are avoided.

Abstract: Provided is a method by which differently-sized chips may be stacked at the wafer level. The wafer level chip stack method utilizes first and second wafer assemblies that support first and second wafers on adhesive tapes. One or both of the supported wafers may be sawed or otherwise divided to obtain separate first and second chips that remain fixed to respective first ring frames. The first and second wafer assemblies may then be positioned and aligned so that a back surface of the second wafer faces an active surface of the first wafer. Each of the second chips may then be bonded to a corresponding first chip to form a chip stack using an adhesive layer. The chip stacks may then be detached from the wafer assemblies and attached to a substrate.
